1. High-speed rail, the environmentally friendly solution for mobility Dr. Michael Schemmer Chairman, UNIFE Transport & Environment WG Senior Director Health, Safety & Environment, Bombardier Transportation

2. 2 Is rail really environmental friendly?

3. 3 Without rail, reduction of CO 2 emissions is impossible!  Currently: rail = 13.5% of all tonkm within the EU  Expected: rail = 14.5% until 2015 Source: Prognos, Basel; UIC, Paris; BMU, Berlin; calculations by Bombardier Transportationr

4. 4 Energy consumption / related CO 2 Emission  Example : Business trip Berlin – Frankfurt ICE, Aircraft (LH-Mix*), Car Incl. Taxi (red) * A310, A320, B737 Source: IFEU, 2002 / Deutsche Bahn AG l / person Kg / person

5. 5 Specific energy consumption (Wh/seat km) Efficiency of energy generation approx. 32% Source: IFEU Heidelberg, 2002 Train utilization Source : Deutsche Bahn AG, 2001

6. 6 Manufacturers: Influencing and documenting Environmental Performance  Increased load factor (passenger-km / offered seat-km) High speed lines are more attractive and thus have a higher load factor Improved space utilisation maximised in terms of seats per length of train  Low energy consumption - thus low emissions of CO 2, NO x, SO 2 Reduced running resistance, dominated by aerodynamic drag Reduced weight Reduced energy losses in e.g. propulsion and auxiliary systems and also in the catenary and feeding system Reduced energy consumption of comfort equipment, e.g. auxiliary equipment Use of energy regeneration Energy efficient driving and “eco-driving”  Environmentally sound materials All materials in the vehicles are known and listed Bombardier has developed a list of Prohibited & Restricted Substances to ensure that no harmful materials are used in the vehicles  High recyclability > 90% (by weight) The vehicles are produced with a high fraction of recycled and recyclable materials Polymers over 100 grams are marked, according to ISO standards, to facilitate recycling  Efficient mode of transport – in terms of land use  Low noise emissions – TSI for high-speed  Environmental Product Declarations (EPD) Product environmental performance is documented in a reliable way according to ISO standards 14021 / 14025 Based on a Life Cycle Assessment (LCA) according to ISO standard 14040 Other environmental documentation: Recycling manual, Environmental assessment report etc.  Low particle emissions – minimised wear and tear

7. 7 Improved energy consumption Measured for trip Stockholm – Västerås (Sweden) Early 1990’s Intercity train (5 cars)  Speed:110 – 130 km/h  Travel time:1:18 min  Energy:0,12 kWh / pkm*  Load factor:35 % Today Regina  Speed:110 – 200 km/h  Travel time:0:53 min  Energy:0,10 kWh / pkm*  Load factor:35 % ~20% reduced energy consumption even though top speed has increased and thus also travel time decreased dramatically! *pkm = passenger kilometer

10. 10 Bombardier High Speed Trains use Synergies from Bombardier Aerospace  Aeroacoustic Sources  Aerodynamic Drag Global ExpressHigh Speed Train  Side Wind Loads Bogie Wing Tips Local Turbulences optimize acoustic and aerodynamic behavior Bombardier Transportation and Aerospace have together put a lot of efforts in developing sophisticated tools to optimize acoustic and aerodynamic behavior of the trains/planes. BT has proven that those tools correctly predict the reality of the trains in service. This means that, we can now really optimize the trains in the design phase when we are introducing new or modified design. TUNNEL

12. 12 PROSPER I & II Projects Objectives:  To increase the overall ”eco-efficiency”/ sustainable performance of new rolling stock  To assist railways in setting up environmental requirements and assessing tenders  To initiate a dialogue with users (railways) and stakeholders (UNIFE, manufacturers) Results of the Project:  a guideline to assist in setting up environmental requirements and evaluating tenders  a set of recommended qualitative environmental specifications (defining performance values, PROSPER II)  a reference document for experience, examples and state of the art of environmental relations and their economic cost/benefit aspects Output: Environmental Guideline for the Procurement of Rolling Stock (UIC Leaflet) Continuation of “Nordic Manual” (1999) PROSPER Partners: www.railway-procurement.org

13. 13 Conclusion  From an environmental point of view, rail (including high-speed) is superior to other modes of transport.  Nevertheless, manufacturers strive for further reduction of negative environmental impacts.  Areas for improvement are primarily: energy efficiency, noise.  Rail is the only solution to reduce or at least stabilize CO 2 emissions from transport.  The true environmental cost (or external cost in general) must be taken into consideration.
